Cassandra Stavrou and Ryan Cohn are the co-founders of Propercorn, the UK's best selling popcorn brand. The pair started the company in 2011, and back then they used a cement mixer and a paint sprayer to cook up their first batches. Today, Propercorn sells a packet of popcorn every second.

In a today's episode, Cassandra and Ryan discuss building a healthy start-up culture from scratch; the keys to a winning sales pitch; and why Winnie the Pooh is an excellent guide to modern life.
